Oral Chemotherapy Drugs: 5 Key Points for Safe & Effective Use

The continuous emergence of new technologies and drugs has diversified cancer treatment methods. However, the most common treatments remain surgery, chemotherapy, and radiotherapy. Among these, oral chemotherapy drugs are increasingly important for patients seeking effective treatment with improved convenience.

What Are Oral Chemotherapy Drugs?

Chemotherapy refers to the use of chemical drugs to kill tumor cells. Once inside the body, these drugs circulate through organs and tissues via the bloodstream. While they target cancer cells, they also affect other rapidly growing cells, leading to side effects such as leukopenia, diarrhea, mouth ulcers, and hair loss.

A classic example is fluorouracil, widely used in gastrointestinal tumor treatment. It interferes with DNA and RNA synthesis in tumor cells, preventing their proliferation.

Evolution of Oral Chemotherapy Drugs

Previously, fluorouracil was only available in injectable form, requiring hospital visits for intravenous administration. This limited its widespread use. In recent years, pharmaceutical companies have developed oral alternatives such as capecitabine tablets and tegafur capsules, which transform into fluorouracil inside the body to exert anti‑tumor effects.

Oral chemotherapy drugs not only eliminate the inconvenience of injections but also improve quality of life, allowing patients to continue treatment in a comfortable environment.

Five Key Points to Consider When Using Oral Chemotherapy Drugs

1. Strict Adherence to Dosage

Patients must follow the prescribed dosage carefully. Do not increase or decrease the dose without medical advice.

2. Keep a Medication Record

Maintain a daily log of dosage, timing, and any side effects. This helps doctors monitor treatment progress and adjust if necessary.

3. Missed Dose Protocol

If you forget a dose, wait until the next scheduled time and take only the regular dose. Never double the dose to compensate.

4. Drug Interactions

Consult your doctor or pharmacist before combining these drugs with other medications to avoid harmful interactions.

5. Report Side Effects Promptly

If you experience gastrointestinal issues, skin reactions, or other discomforts, seek medical advice immediately.

Safe Storage Guidelines

• Store oral chemotherapy drugs away from light in airtight containers.
• Protect from moisture and heat (room temperature should not exceed 25°C).
• Do not store in the bathroom, kitchen, or refrigerator.
• Keep out of reach of children to prevent accidental ingestion.
• Always check the expiration date and discard leftover medication after treatment.

FAQs
